GARETG. HEERMANCE, or PoUGnKEErsIE, NEwroRKl COOKING-STOVE.

n Specification of Letters Patent No. 852, dated July 24, 18738.

To all whomfrit may concern Be it known thatl I, GARET G. HEERMANCE, of the town of Poughkeepsie, in the county of Dutchess and State of New York, have invented a new and useful Cooking-Stove for Burning All Kinds of Coal or Wood; and I hereby declare that the following is a full and eXact-description'of it. Y Thenature of my invention consists in making the'oven round, and its top sloping upward with angle of forty-live degrees, and in making the fiues passup its outer side and over its top to its center where they receive the'smoke pipe and it also consists in making the bottom of the oven turn around in which there is holes to receive pots or boilers havingthe re beneath and the heat of the oven around their tops and the steam or eflluvia of cooking escapes without a tube immediately through a hole in the top of the oven, and this oven with a iue or smoke chamber beneath it, I place on a square combustion chamberof the common or known form, or on two cast iron cylinders commonly called salamanders.

To enable others skilled in the art of making stoves to make and use my inven-4 tion, I will proceed to describe its construction and operation.

Figure l is a perspective front view of one form of my stoves as a whole with the doors of the oven open. Letters a, a, is the bottom plate or hearth thirty two inches in diameter of the common form. b is the draw in each end of the base to receive the ashes from the grate. c c c is the base of the cylinders, between two parallel cleats four and a half inches high, nine and a half inches broad twenty siX inches long having its ends equally distant from the edge of the hearth. dis one of the cast iron cylinders or salamanders for burning coal or wood nine inches high, and inside nine inches in diameter at the bottom and eleven inches atthe top. These cylinders stand on each end of the base leaving an open space between. I use one or both o-f these cylinders as the work or cold requires. The letters e, c, e, is the bevel flange orrim four inches high, of the circular plate m, m Fig. 2, twenty eight inches in diameter, with two opposite holes for the tops of the cylinders, on the external shoulders of which it rests. This plate with its'bevel flange thirty inches in diameter at its top forms the flue or smoke chamber under the bottom of the oven i, i, z' Fig. 1. I

make the oven round twenty sin inches in diameter and its side eight inches high and the top to slope upward all around at an angle of forty five'degrees I divide the sides and top of the oven through the center into two equal parts, and make one half the sliding doors f f, f f sufliciently small' to i i pass under the other half/1., i1., h, hyhfmoving around the pivot y' at theftop, and slidlng 1n a groove in the flat circleo, 0, 0,70 on which the oven rests. I makethe flat circle 0 0, o c three inches broad and thirtycne lnches 1n its `outer diameter. I make in the upper surface of this circlea groove for the sliding doors f f, f f and a smallV inside shoulder for the bottom of the oven i to rest on and on its under surface near its outer edge I make a groove for the top of the bevel ange e e e e V(see Fig. 2). I fasten the larger part of the oven L li It h perma-V nently to this circle `0 `o 0 o, by screws through its iange or edge. -The iues g g g` g are six inchesA wide by two inches deep standing on the flat circle o 0 0 o." These ues I make whole with no under side which is formed b the sides and top` of the larger part ofy the oven. The iues have a collar, la, for a smoke pipe and immediately under this collar k I make'a hole in the top of the oven bywhich the steam or efHuvia from cooking escapes into smoke pipe withoutV a tube. The bottom of the oven i z' i with holes for pots or boilers rests on the inner shoulder of the circle 0 0 0 0, and on the permanent pivot, Z, (Fig. 2,) with wings, n, n, to confine the Haine or heat under the pots. The lower end of the pivot, Z, rests on the center of the circular plate, m, m, `with the bevel ange, c e c c. The letters p p is the back door eight inches high by thirteen inches wide, Q g g the movable lever to turn the bottom of the oven when required. Fig. 2is a semisectional view of my stove as represented by Fig. l by being divided through the longitudinal center of the base. I put the coal or wood into the cylinders through the Y holes in the bottom of the oven. I make in the bottom of the oven z',-z', four ormore holes of different Vdiameters for pots or boilers. I `make the horizontal shaking ate I of two parts, to wit, a ring a half inch broad and thick and eight and ahalf inches in its outer diameter, with a projection on its under side, below the top of the base'to receive a movable lever in front, the 1 other part is a circular grate of the common form with Xed axles resting in two notches in the ring and on a movable pin in the projection, which pin being withdrawn the inner part of the grate revolves. J is a section of the grate I with the movable leverinserted. Y

I-I is a section of the base of the cylinders with three projections on which the grate rests and moves. y

D is the same iiaty circle as o 0 0 0 with a U groove for the sliding doors, a shoulder for the bottom of the oven to rest on, andtwo opposite holes Jfor the lues, through which holes the smoke from the smoke chamber beneath the bottom of the oven passes into A Ais the same plate as m, m, with the bevel flange e c e e resting on one long leg behind and in front on a square Combustion chamber ofthe common or known form, as

Y., to its sides, doors, hearth withlegs is fastened'o-n by two rods and screws through two projections u, u, one each side. o I place on A A the o-ven a' ofthe same form and construction as B, except no back door p p and two narrow flues 3, 3, but one broad flue t, 4,'two inches deep by teny inches wide coming up behind in the center and over the top to the center in front with an oval Vcollar for a smoke pipe. E is the flat circle like D on which the oven C rests. with a hole for the iue. The doors have knobs to move them with and to fastenV them. YI make every part of the above stoves of cast iron of the ordinary thickness sometimes orvin some of the stoves I make the sliding doors of the oven of sheet irony and also some fof its other parts when required. I also make some of 'the stoveV as Y represented by the Fig. l without the back door p p. j

lVhat I claim as my invention and desire to secure by Letters Patent is-` The particular manner in which I have constructed the ovenv of mystove as above set forth; lsaid particular construction consisting in the combination of the sliding doors, movable top,and lues, arranged and operating substantially in the manner above described.
